NexTek Series
Lightweight Dual Drag Race Valve Springs
Features

• Higher natural frequency and lower active mass provides improved valvetrain control and higher RPM potential
• Dual spring design reduces friction, which generates less heat and translates into greatly reduced load loss
• Extensively tested on the Spintron, dyno and race track (including blown nitro engines) and proven highly effective
• Smaller diameter, lightweight dual design allows engine to rev higher with improved valve train control
• Accepts smaller, lighter retainers which also promotes higher revs
• Ultra clean, high tensile strength chrome silicon material
• Super Finished multi-step surface enhancement significantly improves fatigue strength
• Ideal loads for multiple applications with minimal load loss
